Microsoft Released Cumulative Update 6 (KB4012108) for Exchange 2016 today.
This Cumulative Update contains the following:
- Sent Items Behavior Control (My Favorite Feature)
- Original Folder Item Recovery (Many waited for that a while now)
- Latest time zone updates (Matching the may 2017 updates)
- TLS 1.2 Exchange Support Update (I like that a lot!)
The Announcement indicates, that this Release supports .Net 4.7, but the Exchange Support Team is still doing some tests, and you should not install it on your Exchange Servers now.
I leave .Net 4.7 on my WSUS Servers for Exchange and I also blocked the installation in the Registry. Just in case!
A sad thing: There is still an issue on my Windows Server 2016 based Exchange Servers!
But the good news: My Workaround still works!
I recently published a new PowerShell Module to Maintain Exchange Servers. I used the ExchangeNodeMaintenanceMode to install Cumulative Update 6 for Exchange 2016 on my Servers.
These servers are test systems, and I highly recommend you to do the same.
Or wait at least a few days, or even better a few weeks before deploy it to you regular Exchange Servers. Just in case, this release has some surprises.
